Thanks to Steve and everyone else who posted the answer to my poorly
phrased question. What I was really after was information on the
technology of the media that can be used in 1 3B2 floppy drive. There
was a discussion on comp.sys.ibm.pc about a year ago, but I've lost my
notes from that.
Anyway, to put things in context, my "question" was an attempt to make a
poster think about the answer to that question. I already knew.
